How it works
A note
This app helps you remember, but posted street signs and official city rules always control.
Tap the colored curb where you park to see when it gets swept.
Tap a colored curb line to see its schedule. Turn its reminder on from the card that opens.
Your location is used to center the map and, when you tap Park here, to remember where you parked on this device. We don't sell your data.

Curb Alerts covers street sweeping in Denver and San Francisco, and snow emergencies in Minneapolis. For Minneapolis, the map shows which side of each street the city bans parking on, on each day of a declared snow emergency, and the iPhone app can alert you when one is declared. Everything below applies to each city as it does to the others.
Curb Alerts is a reminder tool built to help drivers remember posted street sweeping restrictions in Denver and San Francisco. It is operated by Curb Alerts LLC ("we" and "us" in these terms). By using the app, you agree to use it as an extra reminder and not as a replacement for checking posted signs, city rules, or your own parking situation.
You are responsible for parking legally. Street signs, temporary city notices, emergency restrictions, construction, weather, and official city rules always control over anything shown in this app.
In San Francisco, street sweeping is enforced from the signs posted on each block, and the sign always wins. Our San Francisco map follows the City and County of San Francisco's published schedule, which can differ from the sign on a given block. The hours we show are the posted hours, not a promise of when a sweeper will come, and a 5th-week day or a holiday may be swept or skipped contrary to what the schedule says. Read the sign before you leave your car.
The map, address search, curb colors, and saved curbs are free. In the Curb Alerts iPhone app, street sweeping reminders and Minneapolis snow emergency alerts need a subscription, and one subscription covers every city. It is sold by Apple through the App Store. The plans and their prices are shown in the app and on the App Store before you buy, and a free trial is offered on the yearly plan to people who have not had one.
A subscription renews automatically at the end of each period unless you cancel it at least 24 hours before. Apple charges your Apple ID and handles billing, renewals, cancellations, and refunds; you can manage or cancel your subscription in your iPhone's Settings under your Apple ID. We never see or store your card.
Your reminders will not stop without warning. If a payment fails, or your subscription is cancelled or ends, the app tells you ahead of time and again when your reminders stop, so that a billing problem is never the reason you get a ticket. The same goes for snow emergency alerts: if one is declared while your alerts are off, we send you a single notice saying so.
A snow emergency alert is sent only after a person at Curb Alerts has confirmed the city's declaration, so it can reach you later than the city's own announcement, or not at all. The City of Minneapolis announcement, posted signs and the city's own parking map always control.
We may change, add, pause, or stop features as the app improves.
Curb coverage is best effort and always will be. Each city's published sweeping data is incomplete in places, cities change schedules, and nothing here guarantees that a given block is correct or that a reminder will arrive. See the Disclaimer for what that means in practice.
Please do not misuse the app, interfere with the service, scrape it aggressively, submit false reports, or use it in a way that could harm other users or the city data services it relies on.

Curb Alerts is operated by Curb Alerts LLC, which is the "we" on this page.
We collect only what the app needs to help you create and receive curb reminders. Your location is used to center the map and to remember where you parked, and that parking spot stays on your device. We do not sell your data.
We use this information to show the map, save your alert setup, send test notifications, schedule reminders, confirm your email address, let you reset a forgotten password, troubleshoot bugs, and improve curb coverage. We do not use it for advertising.
The app is hosted on Render, which also hosts the database holding accounts and reminder schedules. It uses browser push services operated by your browser vendor, Apple's push notification service for the iPhone app, map tiles and street data from OpenStreetMap, and street sweeping data published by the City and County of Denver and the City and County of San Francisco, and snow emergency parking data published by the City of Minneapolis. Those services may process basic technical information needed to load maps, routes, and notifications.
One more is involved only if you create an account: Resend delivers the confirmation and password reset emails, which means your email address passes through it. Subscriptions in the iPhone app are sold and billed by Apple through the App Store: we never see your card or your Apple ID. Your device checks with Apple whether your subscription is active and tells us the answer, and Apple itself tells us when a payment fails or a subscription ends, so we can warn you when your alerts are about to stop.
Those emails show our app icon, which your email app loads from our server when it displays the message. That request reaches our server logs the same way loading any page does. We do not use it to see whether you opened an email, and nothing in the app reads it.
Deleting your account from the Account page removes the account, its saved curb sets, every signed-in session, and any outstanding email links, immediately and for good. Reminders you set up on a device keep running unless you turn them off, because they belong to the device rather than to the account.
If you want a copy of what we hold, or want it removed without using the in-app delete, email us at the address below.
You can decline location access, decline notifications, turn off curb reminders, delete saved sets, delete your account, or remove the app from your device.
For privacy questions or a data request, email support@curbalerts.co, or use Report an issue.

Curb Alerts is an informational reminder app. It is not legal advice, not an official service of the City and County of Denver or the City and County of San Francisco, and not a guarantee that you will avoid a parking ticket.
The same is true of the Minneapolis snow emergency map and alerts: they are not an official City of Minneapolis service. The map is built from the city's published open data, where the city's own datasets sometimes disagree, and a snow emergency alert is sent only after we have confirmed the city's declaration. The city's announcement and the posted signs always control.
San Francisco street sweeping is enforced from the posted signs. Our San Francisco map is built from the city's published schedule, which can differ from the sign on a given block, and it shows the hours the schedule posts, not a promise about when a sweeper will come. A 5th-week day or a holiday may be swept or skipped contrary to the schedule. The sign always controls.
Posted signs, temporary restrictions, emergency routes, construction notices, special events, and official city rules may change. You should always check the curb signs where your car is parked before relying on a reminder.
Push notifications depend on your phone, browser, internet connection, battery settings, and hosting services. A reminder may arrive late, fail to arrive, or display outdated information.
This version may not include every sign, exception, or route detail. Please report anything that looks wrong so we can improve it before expanding.
One-time setup
iPhone only sends reminders from apps on your Home Screen. This takes about fifteen seconds.
